Hi ,

Here is your answer :-

The calorie was originally defined as the amount of heat required at a pressure of 1 standard atmosphere to raise the temperature of 1 gram of water 1° Celsius. Since 1925 this calorie has been defined in terms of the joule, the definition since 1948 being that one calorie is equal to approximately 4.2 joules.

The large calorie, food calorie, or kilocalorie (Cal, Calorie or kcal), most widely used in nutrition, is the amount of heat needed to cause the same increase in one kilogram of water. Thus, 1 kilocalorie (kcal) = 1000 calories (cal).

HOPE IT HELPS YOU .
